I had to use my dining room table for a couple of years. It was hard on the back and shoulders cause the machine was too high. And I had to clean everything off of the table every week, (at least) cause we have a small group that meets here one night a week. Though for a while we had meeting here 3 nights a week!!! Sure got in the way of sewing. It was no fun cleaning it all up constantly. Now I have room to leave what I'm working on out!!!
I don't have enough counter space in my Kitchen to do anything but cook on. That would make it hard to get anything done, that and the counter would have to be cleaned up really good so you don't get anything on your fabrics!!!
